With the vast incorporation of electricity, the White City remained open at night, a technological marvel as most of the world still relied on candles or gaslighting. [27]
Moving Walkway
Fairgoers were treated to the first moving sidewalk that looped the 3,500-foot pier in Chicago. For 5 cents a ride, riders could stand or walk. [27]
Dishwasher
As a precursor to the modern dishwasher, in 1850, Joel Houghton patented a machine that splashed waters on dishes. Not satisfied by the largely ineffective device, Jospehine Cochran set out to invent the dishwasher herself. In 1886, she created a hand operated, mechanical machine that sprayed warm, soapy water by using a hand crank. She unveiled this new invention at the 1893 World’s Fair; however, only hotels and restaurants purchased her dishwasher. The general public did not have dishwashers widely until the 1950s. [27]
Cracker Jack
Thought to be the first junk food, the new recipe of Cracker Jacks was introduced by the Rueckheim brothers in 1893. This recipe included popcorn, peanuts, and molasses. [27]
Spray Paint
To paint the "White City" quicker, Joseph Binks, a maintenance supervisor in Chicago, created one of the first versions of spray paint. He combined a hand-operated pump, a tank, and a nozzle planting the seed for the future portable aerosol sprayers developed in 1949. [27]
Ferris Wheel
The first Ferris Wheel was a 264-foot-tall attraction, which could carry an estimated 2,000 people at once. On its first day, the Ferris Wheel had 38,000 people ride for fifty cents a turn. [27]
